Abstract
Procedimiento para controlar el ángulo de extinción de los p rectificadores de corriente, tiristores, de un circuito de puente de tiristores por formación de una señal proporcional al ángulo de extinción en la amplitud, a partir de una magnitud auxiliar de amplitud constante a través de un integrador por cada grupo de rectificadores de conmutación y mediante impulsos iniciales derivados del final de flujo de corriente de los rectificadores individuales por un lado, e impulsos finales derivados del comienzo de tensión de bloqueo positiva en el correspondiente rectificador por otro lado, con extinción del valor de integración de los integradores mediante los impulsos finales del grupo de rectificadores de conmutación que en cada caso es el otro, y selección de valor máximo de los valores de salida de integrador, caracterizado porque la señal de valor máxima formada a partir de los valores de salida de integrador es introducida en cada caso a las entradas de p de los miembros de retención de exploración asociados con los rectificadores individuales, porque en su segunda entrada están conmutados en cada caso los impulsos de tensión individuales mencionados del correspondiente rectificador, los cuales ajustan a los miembros de retención de exploración correspondientemente al valor momentáneo de la señal de valor máximo y a continuación en un miembro con selección de valor mínimo se aprende el correspondiente valor mínimo de los miembros de retención de exploración.
